It is caused by an avian paramyxovirus 1 that has high genomic diversity. In the framework of an international surveillance program launched in 2007, several thousand samples from domestic and wild birds in Africa were collected and analyzed. ND viruses (NDV) were detected and isolated in apparently healthy fowls and wild birds. However, two thirds of the isolates collected in this study were classified as virulent strains of NDV based on the molecular analysis of the fusion protein and experimental in vivo challenges with two representative isolates. Phylogenetic analysis based on the F and HN genes showed that isolates recovered from poultry in Mali and Ethiopia form new groups, herein proposed as genotypes XIV and sub-genotype VIf with reference to the new nomenclature described by Diel’s group. In Madagascar, the circulation of NDV strains of genotype XI, originally reported elsewhere, is also confirmed. Full genome sequencing of five African isolates was generated and an extensive phylogeny reconstruction was carried out based on the nucleotide sequences. The evolutionary distances between groups and the specific amino acid signatures of each cluster allowed us to refine the genotype nomenclature.

It is one of the 14 avian acid motif present at the protease cleavage site of the F0 precursor diseases notifiable to the World Organization for Animal Health of the fusion protein [10]. In virulent isolates, this motif is (Office International des Epizooties, OIE) [2]. The cause of ND, constituted of basic amino acids, and rapid typing of this region by Newcastle disease virus (NDV) or avian paramyxovirus type 1 RT-PCR and sequencing is a good indicator of the NDV (APMV-1), belongs to the Avulavirus genus, Paramyxoviridae family, pathotype. However, other viral factors affect the virulence of and has a negative-sense single-stranded RNA genome of about isolates, so pathogenicity should be confirmed by in vivo tests, 15.2 kilobases.
